摘要

为探讨触头设计解决大电流隔离开关温升过高、动稳定和热稳定性差的问题的措施

笔者分析了大电流隔离开关温升过高、动稳定和热稳定性差的原因

结合一个12 kV大电流隔离开关设计实例介绍了动端触指接触结构

重点介绍了一种用于触头静端的新型的凸圆柱与凹锥面进行导电接触的结构

这两种导电接触形式能够满足大电流隔离开关的特殊要求。

Abstract

In this paper

the reason and solutions of the high temperature-rise value and poor perfomance for short time and peak current withstand capability are discussed.One 12 kV high current disconnector is selected as an design example.The structure of the finger of rotation contact and a new structure of contact

a cylinder contact with a conical surface

used to the static contact

are introduced.Both of them can satisfy particular demands of high current disconnector.
